The Firmware in my charge is 2.2.1 and it says there are no updates available. I bought a Motorola Bluetooth Android Keyboard (Model SJYN0700A). When I try and pair the phone with the keyboard a message flashes on screen for about 3 seconds " enter PIN 17****. There is no where to enter the PIN# then another message pops up "Unable to pair with motorola keyboard, incorrect PIN or password. I tried this on another CHARGE and it does the same thing. I tried it on a HTC Thunderbolt and I was able to enter code and it worked. Is there a OS/software update/patch so I can can use this keyboard I didn't find any other keyboards that were android compliant. I need to be able to use a full size keyboard when i travel.
